AUXILIARY SIGHT FOR FIREARMS.

Patented Nov. 28, 1916.

Application filed November 22, 1915. Serial No. 62,724.

To all 107mm it may concern Be it known that I, EDMUND ALFRED DE- BUCHY, a citizen of the United States, and resident of the town of WVest Hoboken, county of Hudson, State of New Jersey, have invented certain new and useful Improvements in Auxiliary Sights for Firearms, of which the following is a specification.

'The sight is the device by which firearms are aimed at the object at which they are intended to shoot and although there are many different kinds of sightsemployed, all sights may be generally included in two broad classifications. The open sight which is used for general field or sporting purposes where extreme-accuracy is not necessary but where rapidity is more to be desired. Such an open sight usually consists of a member which may be a point or bead and which is secured to the outer end of a gun-barrel and a block having an upwardly projecting portion in which a V-shaped opening is cut, and which is usually secured on the barrel, but at a point close to the firing" mechanism or look as it issometimes called.

A' closed sight usually consists of a bead as the outer member and a disk having a small perforation as the inner or near member of the sight. 7 Such a sight is used for very accurate work and it is usually adj ustable as to elevation and sometimes transversely adjustable to compensate for wind pressures.

The fitting of the separate sights to a gun is a work that. must be most carefully accomplished and therefore it is usually intrusted only to the manufacturer of the gun so that it becomes a custom for the purchaser of a gun to predetermine the kind of sight with which the gun shall be equipped. It sometimes happens, however, that the owner of a gun fitted with open sights will desire to use the gun for more accurate work with the result that a new ordifferent sight must be attached by one entirely familiar with the work of placing-sights. -This often occasions delay and inconvenience and it is to obviate the necessity for this delay and most careful refitting that I have provided a device that may be readily attached to an ordinary open sight and which when so attached will provide all of the advantages of the so called peep-sight.

My invention relates to such an attachment and from the. description which follows, it will appear that when properly constructed, a closed sight may be placed in position by the owner or operator of the gun'with an assurance of the same accuracy that would result were a more complicated closed sight attached by an expert.

The following is what I consider a good means of carrying out this invention, and the accompanying drawing forms a part of the specification, in which Figure 1 shows a rifle with my sight at tached. F ig. 2' a perspective view of the sight. Fig. 2 a clamping means which holds the sight in position. Fig. 3 an elevation of the sight in operable position. Fig. 4L a sight of a modified fornr- Fig. 5 a sight of a further modified form and having a different attaching means, and Fig. 6 a side elevation of the sight shown in Fig. 5.

Similar reference numerals indicate like parts in all the figures where they appear.

In referring to the drawings,it will be noted that I have shown what I will refer to as a rifle. In presenting the rifle no attempt is made to set forth a gun of any particular construction, shape or design, as I desire it understood that my device maybe employed with rifles, guns, or revolvers of almost any type. I will therefore indicate the entire rifle at 1, referring by that character to any firearm equipped with an outer sight 2 and an inner sight. The inner sight here shown is a metallic member having a body portion 3 adapted to be attached to the gun and an upwardly extending portion 4-, projecting upward from the surface of the gun. In the sight shown the outwardly projecting member is curved and by means of a screw 5 and the slight flexibility of the body portion of the sight, the upwardly extending part is brought to a proper elevation.

In the upwardly extending portion of the sight is a V shaped aperture 6 shown in dotted lines in Fig. 3. This together with the part 2 provides the means bywhich the gun is usually aimed.

To produce a closed or peep-sight, I provide a member shown in 2 and 2 which consists of a forward plate 7 having a centrally disposed counter-sunk aperture 8 and a plu rality of inwardly projecting recesses 9 and 10.

Formed integral with the plate 7 is a back plate 11 having a perforation in direct clamp.

The clamp referred to should be formed of hardened steel and is provided with inwardly projecting tongues 15 and 16 adapted to pass into the recesses 9, 10 and .12 and to engage upon the portion 6 of the open sight. The forward end of these tongues 15' and 16 may be sharpened as shown in Fig. 3 so that a more firm engagement will result. To prevent my device from moving upward, I provide two downward extensions 17 and 18 formed integral with the tongues 15 and 16 and I connect these extensions together by means of a bar 19 which will pass under and engage with the curved portion 4: of the open sight. It will be noted that in placing my device, the perforation 8 isso arranged that it will assume a position directly in line with the lowermost portion or apex of the V, 6 and therefore insure the proper alinement of my auxiliary sight.

When an open sight is again desired, the clamp] 'may be readily removed and my closed sight drawn upward out of engagement with the open sight of the rifle and it will appear obvious that my device. may be attached or removed at will by the operator and without delay and that it may be carried in the pocket ready for instant attachmentf I have found that a closed sight having a greaterarea than the one thus far described may be preferred from the fact that in using closed sights, it is desirable to exclude cross or confusing lights. I may therefore round the top of my sight in the manner indicated at 20 in Fig. 4, or I maymake the back plate circular as shown at 21 in Fig. 5 slightly Copies of this'patent may be obtained for five cents each, by

increasing the diameter of the counter-sunk portion indicated at 2-9. in this figure so as to obtain all of the advantages of a large sight sometimes called a wind-sight. I may also provide other and simpler means for attaching my auxiliary sight, such a means as shown in Figs. 5 and 6 where the bottom portion of the front plate is inturned as shown at This sight may be of flexible steel or other suitable material and may be attached by being snapped over the open sight or being removed inwardly from a side of the member 6. y

Other modification in size, shape or de sign, may be made to meet different conditions and changes not here referred to, within the scope of the appended claims with-. out departing from the principle or sacrificing the advantages of the invention.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is 1. A rifle having an ordinary notched sight and an auxiliary sight comprising a perforated plate and'a frictional clamp adapted to secure it in position with the perforation coinciding with the notch of said sight.

2. The combination with a notched sight for firearms of a perforated front and back plate formed integral and adapted to engage upon said sight and cooperate therewith as and for the purpose set forth.

3. The combination with a notched sight for firearms of a perforatedfront and back plate formed integral and adapted to engage, upon said sight with said perforation coinciding with the notch thereof. and a clamp adapted to secure said device in operable position upon said sight.

Signed at New York, city, county and State of New York, this 13th day of Nov. 1915, in the presence of two witnesses.
